4K-MEMS Technology
Too small to see, too bright to ignore.
4K-MEMS broadband IR emitters are the world’s first thermal emitter ready for the consumer market: sized to be embedded in the smallest of spaces., manufactured and packaged at a wafer scale to allow mass production.
We build lighting solutions that seamlessly integrate with tomorrow’s sensing platforms. By customizing the illumination to the application, our emitters set a new standard for infrared lighting. The micro-emitters are based on inspired designs, novel material development, and cutting-edge wafer level micro-manufacturing processes.
Broadband IR, where you need it, when you need it.
Our Mission
4K-MEMS SA develops disruptive miniaturized light sources enabling new architectures in machine vision, hyperspectral imaging, and portable spectroscopy. Our revolutionary light sources are designed for deep integration in embedded analysis modules. 4K-MEMS provides NIR/SWIR integrated lighting solutions needed for these emerging applications.
4K-MEMS addresses the growing need for quality broadband IR illumination, resulting from the recent technology breakthroughs in IR detection, chip-sized sensor modules, and evaluation algorithms. Soon, chemical identification will become ubiquitous in consumer electronics – including cell phones. 4K-MEMS will help make that happen.
Current projects
OMICSENS aims to develop a groundbreaking omics measurement platform, initially focused on improving non-small cell lung cancer (NSCLC) prognosis by enabling timely and accurate detection of Tyrosine Kinase Inhibitor (TKI) resistance linked to Epidermal Growth Factor Receptor (EGFR) mutations. As part of the project, 4K-MEMS is developing novel materials and SWIR emitter arrays. The platform will feature a nanophotonic biosensor, a highly absorbent nanochip for analyte detection, and a metamaterial-based detector with AI-driven analyte quantification. It will also incorporate a microfluidics system for efficient sample delivery and offer a customizable design to optimize treatments for various cancers.
The HyperImage project aims to create a versatile, fast, and affordable spectral imaging platform for both long- and short-range applications. Key technical goals include developing new photonic components, high-performance sensors, and advanced tunable optics. 4K-MEMS is contributing by developing novel 1D emitter array modules for line illumination, enhancing the platform's capabilities. The project also focuses on modular designs for automated material analysis and quality control, integrating lightweight spectral imaging systems into robots and vehicles, and building a cloud-based platform for spectral image analysis. Ultimately, the project seeks to validate the technology in various industries and establish commercialization paths and European value chains for spectral imaging systems across key markets.
EXQUISITE
